Nema recently published a white paper on outdoor lighting guidelines. This is an interesting read for those who want to keep up-to-date on the types of design and equipment required to comply with the many lighting ordinances popping up around the country.

It also includes an excellent glossery of lighting terms (many of them new). For instance, do you know the difference between discomfort glare and disability glare? Do you know what a BUG rating is? (No, it's not how many bugs are attracted to a light.)
